Therefore, by adjusting the physical condition to the predetermined atmospheric pressure in the pressure adjustment chamber 12, even if the athlete or the like moves into the cavity 2, the physical condition is not affected by the reduced pressure. Also, by alternately opening and closing the two doors (not shown), air on the atmosphere 39 side does not flow,
The pressure in the cavity 2 is maintained at the predetermined pressure. Further, since the strong rock 40 receives the load generated by the pressure difference from the atmospheric pressure due to the decompression of the cavity 2, the cavity 2 can be constructed at a lower cost than provided on the ground. The temperature and humidity in the cavity 2 are adjusted to predetermined values by the air conditioner 11, but the temperature and humidity change is small throughout the year since the cavity 2 is provided in the rock. That is, the underground temperature is lower than the atmospheric temperature in summer and higher than the atmospheric temperature in winter, so that less energy is consumed for controlling the temperature and humidity in the cavity 2. Further, since the airtightness of the bedrock 40 is good, the energy required for adjusting the air pressure can be reduced. Therefore, the energy required for maintaining the predetermined atmospheric pressure in the cavity 2 and controlling the temperature and humidity has an energy saving effect as compared with the case where the cavity is provided on the ground. Further, the inner peripheral surface 40 of the cavity 2
a is covered with a waterproof sheet 20, and groundwater or water condensed on the wall surface oozing out from the rock to the inner peripheral surface 40a is blocked by the waterproof sheet 20, collected in the trench 22, and drained to the outside. The athlete can comfortably train without rain, and since the exercise equipment such as the truck 31 does not get wet, maintenance and management are easy.

In the above-mentioned embodiment, as shown in FIG. 1, the exercise building in which the semi-spheroidally formed cavity 2 is connected to the atmosphere 39 through the horizontal tunnel 3 has been described. May have any shape as long as exercise equipment such as a pool 30 and a truck 31 can be provided therein, and the tunnel 3 does not necessarily need to be provided horizontally.
